Introduction

In this report, we extract information about published JOSS papers and generate graphics as well as a summary table that can be downloaded and used for further analyses.

Load required R packages

suppressPackageStartupMessages({
    library(tibble)
    library(rcrossref)
    library(dplyr)
    library(tidyr)
    library(ggplot2)

## Keep track of the source of each column
source_track <- c()

## Determine whether to add a caption with today's date to the (non-interactive) plots
add_date_caption <- TRUE
if (add_date_caption) {
    dcap <- lubridate::today()
} else {
    dcap <- ""
}
## Get list of countries and populations (2022) from the rworldmap/gt packages
data("countrySynonyms")
country_names <- countrySynonyms |>
    select(-ID) |>
    pivot_longer(names_to = "tmp", values_to = "name", -ISO3) |>

## Country population data from the World Bank (https://data.worldbank.org/indicator/SP.POP.TOTL),
## distributed via the gt R package
country_populations <- countrypops |> 
    filter(year == 2022)
## Read archived version of summary data frame, to use for filling in 
## information about software repositories (due to limit on API requests)
## Sort by the date when software repo info was last obtained
papers_archive <- readRDS(gzcon(url("https://github.com/openjournals/joss-analytics/blob/gh-pages/joss_submission_analytics.rds?raw=true"))) %>%
    dplyr::arrange(!is.na(repo_info_obtained), repo_info_obtained)

## Similarly for citation analysis, to avoid having to pull down the 
## same information multiple times
citations_archive <- readr::read_delim(

Collect information about papers

Pull down paper info from Crossref and citation information from OpenAlex

We get the information about published JOSS papers from Crossref, using the rcrossref R package. The openalexR R package is used to extract citation counts from OpenAlex.

## Fetch JOSS papers from Crossref
## Only 1000 papers at the time can be pulled down
lim <- 1000
papers <- rcrossref::cr_works(filter = c(issn = "2475-9066"),

                            limit = lim, offset = i * lim)$data)
    i <- i + 1
}
papers <- papers %>%
    dplyr::filter(type == "journal-article") 
dim(papers)
## [1] 2548   28
## A few papers don't have DOIs - generate them from the URL
noaltid <- which(is.na(papers$alternative.id))
papers$alternative.id[noaltid] <- gsub("http://dx.doi.org/", "",
                                       papers$url[noaltid])

## Get citation info from Crossref and merge with paper details

Pull down info from Whedon API

For each published paper, we use the Whedon API to get information about pre-review and review issue numbers, corresponding software repository etc.

    whedon <- c(whedon, a)
    p <- p + 1
    a0 <- a
    a <- tryCatch({
        jsonlite::fromJSON(
            url(paste0("https://joss.theoj.org/papers/published.json?page=", p)),
            simplifyDataFrame = FALSE
        )}, 
        error = function(e) return(numeric(0))
    )
}

Tabulate number of missing values

In some cases, fetching information from (e.g.) the GitHub API fails for a subset of the publications. There are also other reasons for missing values (for example, the earliest submissions do not have an associated pre-review issue). The table below lists the number of missing values for each of the variables in the data frame.

DT::datatable(
    data.frame(variable = colnames(papers),
               nbr_missing = colSums(is.na(papers))) %>%
        dplyr::mutate(source = source_track[variable]),
    escape = FALSE, rownames = FALSE, 
    filter = list(position = 'top', clear = FALSE),
    options = list(scrollX = TRUE)
)

Number of published papers per month and year

ggplot(papers %>% 
           dplyr::mutate(pubmonth = lubridate::floor_date(published.date, "month")) %>%
           dplyr::group_by(pubmonth) %>%
           dplyr::summarize(npub = n()), 
       aes(x = factor(pubmonth), y = npub)) + 
    geom_bar(stat = "identity") + theme_minimal() + 
    labs(x = "", y = "Number of published papers per month", caption = dcap) + 
    theme(axis.title = element_text(size = 15),
          axis.text.x = element_text(angle = 90, hjust = 1, vjust = 0.5))

ggplot(papers %>% 
           dplyr::mutate(pubyear = lubridate::year(published.date)) %>%
           dplyr::group_by(pubyear) %>%
           dplyr::summarize(npub = n()), 
       aes(x = factor(pubyear), y = npub)) + 
    geom_bar(stat = "identity") + theme_minimal() + 
    labs(x = "", y = "Number of published papers per year", caption = dcap) + 
    theme(axis.title = element_text(size = 15),
          axis.text.x = element_text(angle = 90, hjust = 1, vjust = 0.5))

The plots below illustrate the fraction of pre-review and review issues closed during each month that have the ‘rejected’ label attached.

ggplot(all_rejected, 
       aes(x = factor(closedmonth), y = nbr_rejections/nbr_issues_closed)) + 
    geom_bar(stat = "identity") + 
    theme_minimal() + 
    facet_wrap(~ itype, ncol = 1) + 
    labs(x = "Month of issue closing", y = "Fraction of issues rejected",

    theme(axis.title = element_text(size = 15),
          axis.text.x = element_text(angle = 90, hjust = 1, vjust = 0.5))

Citation distribution

Papers with 20 or more citations are grouped in the “>=20” category.

ggplot(papers %>% 
           dplyr::mutate(citation_count = replace(citation_count,
                                                  citation_count >= 20, ">=20")) %>%
           dplyr::mutate(citation_count = factor(citation_count, 
                                                 levels = c(0:20, ">=20"))) %>%
           dplyr::group_by(citation_count) %>%
           dplyr::tally(),
       aes(x = citation_count, y = n)) + 
    geom_bar(stat = "identity") + 
    theme_minimal() + 
    labs(x = "OpenAlex citation count", y = "Number of publications", caption = dcap)

The table below sorts the JOSS papers in decreasing order by the number of citations in OpenAlex.

Power law of citation count within each half year

Here, we plot the citation count for all papers published within each half year, sorted in decreasing order.

ggplot(papers %>% dplyr::group_by(halfyear) %>%

Pre-review/review time over time

In these plots we investigate whether the time a submission spends in the pre-review or review stage (or their sum) has changed over time. The blue curve corresponds to a rolling median for submissions over 120 days.

## Helper functions (modified from https://stackoverflow.com/questions/65147186/geom-smooth-with-median-instead-of-mean)
rolling_median <- function(formula, data, xwindow = 120, ...) {
    ## Get order of x-values and sort x/y
    ordr <- order(data$x)
    x <- data$x[ordr]
    y <- data$y[ordr]
    
    ## Initialize vector for smoothed y-values
    ys <- rep(NA, length(x))
    ## Calculate median y-value for each unique x-value
    for (xs in setdiff(unique(x), NA)) {
        ## Get x-values in the window, and calculate median of corresponding y
        j <- ((xs - xwindow/2) < x) & (x < (xs + xwindow/2))
        ys[x == xs] <- median(y[j], na.rm = TRUE)
    }
    y <- ys
    structure(list(x = x, y = y, f = approxfun(x, y)), class = "rollmed")
}

predict.rollmed <- function(mod, newdata, ...) {

Languages

Next, we consider the languages used by the submissions, both as reported by Whedon and based on the information encoded in available GitHub repositories (for the latter, we also record the number of bytes of code written in each language). Note that a given submission can use multiple languages.

## Language information from Whedon
sspl <- strsplit(papers$languages, ",")
all_languages <- unique(unlist(sspl))
langs <- do.call(dplyr::bind_rows, lapply(all_languages, function(l) {
    data.frame(language = l,
               nbr_submissions_Whedon = sum(vapply(sspl, function(v) l %in% v, 0)))
}))

## Language information from GitHub software repos
a <- lapply(strsplit(papers$repo_languages_bytes, ","), function(w) strsplit(w, ":"))
a <- a[sapply(a, length) > 0]
langbytes <- as.data.frame(t(as.data.frame(a))) %>% 
    setNames(c("language", "bytes")) %>%
    dplyr::mutate(bytes = as.numeric(bytes)) %>%
    dplyr::filter(!is.na(language)) %>%
    dplyr::group_by(language) %>%
    dplyr::summarize(nbr_bytes_GitHub = sum(bytes),
                     nbr_repos_GitHub = length(bytes)) %>%
    dplyr::arrange(desc(nbr_bytes_GitHub))

    labs(x = "", y = "Number of submissions", caption = dcap) + 
    theme(axis.title = element_text(size = 15))

    escape = FALSE,
    filter = list(position = 'top', clear = FALSE),
    options = list(scrollX = TRUE)

    geom_point() + scale_x_log10() + scale_y_log10() + geom_smooth() +

Citation analysis
